The sister of Sarabjit Singh, the death row prisoner who died today, accused Pak of backstabbing India and said she would fight for 'other Sarabjits' languishing in Pak jails.

The sister of Sarabjit Singh, the death row prisoner who died on Thursday, accused Pakistan of backstabbing India and said she would fight for 'other Sarabjits' languishing in Pakistani jails.

An emotional Dalbir Kaur, who has been fighting for the release of Sarabjit, said successive governments in the country failed to bring back her brother who was a victim of mistaken identity.

"They backstabbed Atal Bihari Vajpayee first. Now they backstabbed (Prime Minister) Manmohan Singh. They have now attacked India's emotions by killing my brother. My brother has become a martyr for the country," she told reporters in New Delhi.

She said that she has been raising the issue of Sarabjit since 2005 but no steps were taken by the government for his release. "If the steps had been taken, he would have been alive now," she said.

Kaur also claimed that a Pakistani human right activist had demanded at least Rs two crore for the release of her brother.

"If I had given Rs 2 crore..., my brother would have been alive now. The person demanded Rs 2 crore for the release of my brother. When I said that I am from a poor family, that person said if you cannot give Rs 25 crore, you will have to give at least Rs 2 crore.

"That person told me that if you gave the money in the morning, Sarabjit will be released in the evening and if you give the money in the evening, he will be set free the next morning," he alleged.

She said that home minister Sushilkumar Shinde has assured her all help and that Sarabjit will be honoured.

49-year-old Sarabjit died of cardiac arrest in a Lahore hospital in the wee hours today after being comatose for nearly a week following a brutal assault by fellow inmates in a high-security Pakistani jail.
